Linux Command Complete Reference: A Must-Have Handbook for Beginners
This article introduces the basics of Linux commands and commonly used tools, covering core operations and beginner tips. The basic command format is "command [options] [arguments]". Essential beginner tips include: using --help or man for help, Tab completion, Ctrl+C to interrupt, Ctrl+L to clear the screen, and ↑/↓/Ctrl+R to manage history commands. Core operations: Use ls (-l/-a/-h) to view files and directories, cd to switch directories (relative/absolute paths and ~/. ..), touch/mkdir to create files/directories, and cp/mv/rm to copy, move, and delete (be cautious with rm). For system information, use uname -a, uptime, df -h/free -h, and ps/top to manage processes. For text processing, use cat/head/tail to view files and grep -r to search for text. Software package management is divided into Ubuntu (apt) and CentOS (yum), requiring sudo for privilege elevation. Beginner pitfalls: Pay attention to permissions (sudo), avoid dangerous commands (e.g., rm -rf *), and practice basic commands (ls, cd, etc.) to quickly master daily operations.

This article introduces the learning and use of the Linux command line. The reason for learning the command line is its directness and efficiency, which is suitable for server management, can complete complex tasks, and is more flexible than the graphical interface. Basic file directory operations include ls (list directories, e.g., ls -la shows detailed hidden files), cd (change directory, e.g., cd ~ returns to the home directory), pwd (show current path), mkdir (create directories), touch (create empty files), rm (delete, e.g., rm -rf is used with caution), cp (copy), mv (move/rename), etc. It should be noted that dangerous operations such as rm -rf require special caution. Efficiency tips include: shortcuts (Ctrl+C to interrupt, Ctrl+D to exit, etc.), wildcards (* for batch file matching), pipes | to combine commands (e.g., ls | grep "txt"), background operation &, using --help or man to check help, history commands (history) and Ctrl+R for search. Common problem solutions: For insufficient permissions, use sudo to elevate privileges; check command spelling or consult help if there is an error; exit with exit or Ctrl+D. Summary: The command line is a set of tools that can be mastered with more practice. Platforms like Runoob and Learn Linux Terminal are recommended for learning.
